(CNN) —It was a hot-button trial that drew comparisons to the proceedings against George Zimmerman in the killing of Florida teenager Trayvon Martin. The outcome, however, was vastly different.

The jury in the case of Michael Dunn found him guilty Saturday night on four charges, including three of attempted second-degree murder, but they couldn't reach a verdict on the most significant charge -- first-degree murder in the death of 17-year-old Jordan Davis.

The decision came on the eve of what would have been Davis' 19th birthday.
